First draft.

This document defines an extensible bookmark element pointing to a Pubsub node, compatible with the extensions defined in PEP Native Bookmarks (XEP-0402) XEP-0402: PEP Native Bookmarks <https://xmpp.org/extensions/xep-0402.html>..

This bookmarks elements are always listed as Pubsub items allowing an entity to discover and explore a list of bookmarks listed by another entity. For example in Server-side spaces (XEP-0503)XEP-0503: Server-side spaces <https://xmpp.org/extensions/xep-0503.html>. it allows a Space to list Pubsub nodes besides MUCs in a Space and in Pubsub Subscription (XEP-0330) XEP-0330: Pubsub Subscription <https://xmpp.org/extensions/xep-0330.html>. it allows an entity to share Pubsub nodes it subscribed to.

Information about a Pubsub Node Bookmark is provided by the entity. The bookmark container is defined as a classic <pubsub-node/> element, qualified by with theses specific constraints:

Name Type Description Support
jid attribute The node jid address REQUIRED
node attribute The node node REQUIRED
<extensions/> element XML Elements A set of child elements (of potentially any namespace). Clients MUST preserve these (particularly preserving unknown elements) when editing items. OPTIONAL

The aim of this XEP is to allow an entity to handle a list of subscriptions. To simplify the managment of this list the ID of the Publish-Subscribe (XEP-0060) XEP-0060: Publish-Subscribe <https://xmpp.org/extensions/xep-0060.html>. items MUST be the Pubsub URI of the node as defined in Publish-Subscribe (XEP-0060) XEP-0060: Publish-Subscribe <https://xmpp.org/extensions/xep-0060.html>.#impl-uri without the 'xmpp:' part.
